Relationship between seminal vesicle displacement and distribution of hydrogel spacer within the perirectal space in prostate radiotherapy
In conclusion, SV cranial displacement was influenced by HS lateral distribution of ≥1.00 cm in the upper two slices. Therefore, when the sigmoid colon or small bowel is depressed in rectovesical excavation and SV needs to be included in the target volume, HS insertion should be performed carefully.PMID:37719041 | PMC:PMC10502802 | DOI:10.3892/mco.2023.2674

Dosimetry and acute radiation enteritis comparison between prone and supine position in IMRT for gynecological cancers
CONCLUSION: Prone position in IMRT for gynecological cancers could significantly reduce radiation dose to the small bowel and colon, which would decrease the occurrence and severity of acute intestinal side effects possibly.PMID:37621141 | DOI:10.1002/acm2.14135

Cancer Control, Toxicity, and Secondary Malignancy Risks of Proton Radiation Therapy for Stage I-IIB Testicular Seminoma
CONCLUSIONS: Cancer control and toxicity outcomes using proton RT in stage I-IIB testicular seminoma are consistent with existing photon-based RT literature. However, proton RT may be associated with significantly lower SMN risks.PMID:37408671 | PMC:PMC10318216 | DOI:10.1016/j.adro.2023.101259

In silico comparison of whole pelvis intensity-modulated photon versus proton therapy for the postoperative management of prostate cancer
CONCLUSION: IMPT provides comparable target coverage to IMRT when treating prostate cancer with WPRT in the postoperative setting while significantly reducing dose to OARs. These data can inform the future clinical management and delivery of post-prostatectomy irradiation for prostate cancer.PMID:37345868 | DOI:10.1080/0284186X.2023.2224925

Revisiting the Radical Radiotherapy-Radiochemotherapy Results in Anal Canal Cancers: (TROD Gastrointestinal Group Study 02-005)
CONCLUSION: Radiochemotherapy is the primary treatment for anal canal cancer and advanced radiotherapy techniques may increase survival by reducing side effects and improving treatment continuation. Higher treatment doses require further investigation. The efficacy of treatment can be improved by including patients treated with modern radiotherapy techniques in multicenter prospective studies using new and more effective chemotherapy and immunotherapy agents.PMID:37336706 | DOI:10.1016/j.clcc.2023.05.004

Long-Term Patient-Reported Quality of Life of Anal Cancer Survivors Treated with Intensity Modulated Radiation Therapy and Concurrent Chemotherapy: Results from a Prospective Phase II trial
CONCLUSIONS: When compared with historical data, IMRT is associated with reduced long-term impacts on QOL. The majority of patients treated with IMRT experienced clinically significant recovery of function and improvement in QOL over 5 years after completion of treatment. The study noticed that specific toxicities such as chronic diarrhea, fecal incontinence urinary and sexual dysfunction were primarily responsible for deterioration of the long-term QOL. Future research aimed at reducing such toxicities is needed to further improve long-term QOL in anal cancer.PMID:37148982 | DOI:10.1016/j.ijrobp.2023.04.023

Validation of prediction models for radiation-induced late rectal bleeding: evidence from a large pooled population of prostate cancer patients
CONCLUSION: Five published NTCP models developed on non-contemporary cohorts were able to predict a relative increase in the toxicity response in a more recent validation population. Compared to QUANTEC findings, dosimetric results pointed toward mid-high doses of rectal DVH. The external validation cohort confirmed abdominal surgery and cardiovascular diseases as risk factors.PMID:36934896 | DOI:10.1016/j.radonc.2023.109628
